#3521 closed Bug (No Bug)

Au3Check is not able to recognize Global variables declared inside functions if the variables are used above the function declaration

Reported by: TheDcoder Owned by:
Milestone: Component: Au3Check
Version: 3.3.14.1 Severity: None
Keywords: Cc: Jos

Description

Au3Check is not able to recognise Global variables declared inside functions if the variables are used above the function declaration.

Here is an example script which demonstrates this:

CreateVariable()

ConsoleWrite($sGlobalVariable & @CRLF)

Func CreateVariable()
	Global $sGlobalVariable = "Foobar"
EndFunc

Au3Check throws a nasty warning if you run the code above:

>"C:\Program Files (x86)\AutoIt3\SciTE\..\AutoIt3.exe" "C:\Program Files (x86)\AutoIt3\SciTE\AutoIt3Wrapper\AutoIt3Wrapper.au3" /run /prod /ErrorStdOut /in "C:\Users\TheDcoder\Desktop\AIO AutoIt Test Script.au3" /UserParams

This isn't a bug but poor programming.
Au3Check reads the script line by line from the first line to the last. It doesn't execute the script. Because you're trying to access a global variable that hasn't been declared yet (at that point in the script read), you get an error.

I know that it is not unintentional but Au3Check should be able to detect such situations... There are times when you have to declare Global variables inside functions, something like GUI_CreateMainWindow.

Show example on the forum, and there we can discuss
